Hello Elizabeth,
I take it your machine is a self wind bobbin, thread the machine as normal all the way and through the needle, make sure you have selected straight stitch and the presser foot is up, open the slide plate and push the lever over to raise the winder, wind the thread round the presser foot screw to take a grip and press on the foot control lightly until you have enough thread, close the slide plate and pull the thread to the back of the machine and sew.
